Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Humboldt you can estimate when it's the best time to plant hamelia by reviewing the USDA zone info.

Planting Calendar for Hamelia

Frost tolerance for hamelia:	Not tolerant of frost.
When to plant:	After the last frost.

Since hamelia are not cold tolerant it is necessary to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant hamelia in Humboldt is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant hamelia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your hamelia may not have a chance to fully mature. If you are starting your hamelia indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

Since the USDA zone info for Humboldt is not always accurate the actual date of last frost will vary from year to year. Since half of the time in Humboldt you get a frost after April 15 be ready to protect your hamelia if you have a surprise late frost.
